Unboxing check: ① confirm all listed accessories are present; ② check body, tanks and pitcher for scratches or dents; ③ peel off protective film on body and filters; ④ if anything is missing or damaged, contact the store where you purchased.
Placement & Installation
The G3Pro is a no-install countertop unit — no inlet or drain connection needed. Just add tap water. The placement must meet these requirements:
Placement requirements:
1. Choose a well-ventilated, level and stable surface, away from direct sunlight and heat sources.
2. Leave ventilation space around the unit and a gap from the wall at the back.
3. The surface must support the unit (gross weight ~7.7kg); avoid uneven or wobbly surfaces.
4. A properly rated 3-prong outlet within the 1.5m cord reach.
5. The raw tank is on the side; leave one-hand clearance to slide it out.
Before first power-on:
1. Confirm the raw tank and pitcher are correctly seated.
2. Confirm filters are screwed in firmly.
3. Fill the raw tank with municipal tap water (5℃-35℃).
4. Confirm the power voltage matches the rating plate, then power on and follow the flushing guide below.
New Unit Flushing Guide
Before first use, flush the unit to activate filters and clean pipes. A new unit and filters may carry a slight odor — be sure to complete the flushing. The more you flush, the better the water taste.
Step 1: Air Out. Unbox the unit; remove the raw tank, pitcher, pitcher lid and top cover. Air out in a cool, ventilated, dry place for 8-12 hours (adjust for actual odor).
Step 2: Power On & Purify. Put the pitcher back, fill the raw tank with tap water and replace it. Power on; the water-drop purification icon appears. Wait ~10 minutes until the purified-water light goes off. The first cycle fills empty filters and pipes, so it uses a lot of raw water.
If a water-change prompt appears during purification, pour out the remaining waste water, refill, and let it continue.
Step 3: Drain Cold Water (repeat 3 times). Remove the full pitcher, empty the purified water, reinsert it; the unit purifies again. When done, repeat — emptying the pitcher 3 times in total.
Step 4: Flush with 45℃ Water (repeat 1-2 times). After purification, place a heat-resistant container (3.5L+) under the spout, tap the 45℃ icon, press "Dispense/Stop"; the red dispense light comes on; wait for it to stop automatically.
Step 5: Flush with 98℃ Water (repeat 1-2 times). After purification, tap the 98℃ icon, press "Dispense/Stop"; wait for automatic stop. Beware of hot water splashing.
Step 6: Done. After these steps the unit is ready. For the first 3 days, run one drain cycle daily to fully activate the filters.
Use at High Altitude
Boiling point note: At high altitude, lower air pressure means water boils below 100℃. Heating is affected by altitude; above 1,800m the unit may not reach the set temperature. Please consider this before ordering.
Daily Use
Dispensing Water
Ambient water: Press "Dispense/Stop" directly; the spout lights blue and ambient water flows. Press again to stop.
Warm / hot water:
1. Tap the temperature key to choose (ambient ~ 98℃, 7 levels).
2. Tap the volume key to choose (60~500mL, 6 levels).
3. Press "Dispense/Stop"; the red light comes on and water flows.
4. It stops automatically at the set volume; press again during dispensing to stop manually.
Temperature Presets & Scenarios
The G3Pro offers 7 levels from ambient to 98℃ with 3-second spin-flow instant heat. Recommended uses:
| Temperature | Recommended Use |
|---|---|
| Ambient | Direct drinking, hydration, pet water, humidifier/coffee-machine refill |
| 45℃ | Baby formula, morning warm water; not too hot, preserves formula nutrition |
| 55℃ | Honey water, warm drinks, comfortable to sip |
| 65℃ | Prepared drinks, baby complementary-food temperature |
| 75℃ | Green/white tea; avoids scalding leaves |
| 85℃ | Coffee, oolong, black tea |
| 98℃ | Boiling water; instant noodles, tea, soup and porridge |
Volume supports 60/90/120/200/300/500mL fixed levels with auto stop, suiting bottles, cups and sport bottles. Above 1,800m altitude, low pressure may prevent reaching the set temperature.
Smart Features
G-Radar Smart Night Light: In standby (screen dimmed), placing a cup under the spout automatically lights the screen interaction area and raw-tank lighting — easy dispensing in the dark.
Smart Child Lock: Long-press the "60mL" volume icon for 5 seconds; release after the beep to toggle child-lock mode. When on, the child-lock icon lights and the raw-water TDS shows "LOC"; no dispensing can occur, preventing accidental burns or spills from children and pets. Child lock is off by default on a new unit or after a power reset.
Smart Screen-Off Eco: Auto screen-off when idle; ~1 kWh per 500 standby hours. Tap any key to wake the screen to full brightness.
Real-Time Water Quality: Raw and purified TDS values are displayed, so water quality is visible. Temperature, volume, tanks and filter life are all clear at a glance.
Side Tank Design
5L side tank: The innovative side-tank design is ergonomic, greatly reducing bending during water changes — even the elderly can change water easily. The 5L large capacity means continuous drinking, enough for 3-4 people for a day.
Filters & Care
Filter Structure & Life
The G3Pro uses three independent filters — replace whichever one reaches the end of its life instead of replacing the whole set. The screen shows remaining filter life in real time and reminds you when due.
| Stage | Replace Cycle | Function |
|---|---|---|
| Stage 1 | ~6-8 months | Pre-composite filter, melt-blown PP + sintered carbon; traps sediment, rust and impurities; adsorbs chlorine, color and odor |
| Stage 2 | ~2-3 years | RO reverse-osmosis filter (Japan Toray); filters bacteria, heavy metals and scale; precision 0.0001 micron |
| Stage 3 | ~6-8 months | Post-composite filter, coconut-shell carbon + natural mineral media; suppresses microbes, improves taste, releases beneficial minerals |
Actual filter life depends on power-on time after activation, local water quality and dispensed volume; follow the screen indicator.
Replacing Filters
Spin ID sensor reset. When a filter's life shows blank flashing with beeps, it needs replacing. Using filter #1 as an example:
1. With the unit not purifying, cut the power and unplug.
2. Remove the top cover and find the old filter to replace.
3. Follow the mark, turn from "locked" to "unlocked" and pull out the old filter; within 30s the screen shows L1 (L2 for filter #2, L3 for #3) and beeps.
4. Insert the new filter and turn from "unlocked" to "locked"; L1 disappears with a beep and the bar fills — replacement complete.
5. Drain 2-3 times after replacement before normal use.
No home visit needed; you can replace filters yourself. If the filter indicator does not change within 30s after screwing in, pull it out and reinsert, repeating until it auto-resets.
Notes:
1. Do not turn a filter during chip recognition, or you may damage the chip or interrupt sensing and fail the reset.
2. Each filter chip can reset only its own filter once; only replace when the life system prompts you.
3. After installing a new filter, follow the new-unit flushing method and empty the pitcher three times to fully soak it.
Use only Bewinch original filters; non-original parts may cause substandard water quality or unit failure.
Daily Cleaning & Care
Raw water tank: The 5L side tank is quick-release; clean every 1-2 weeks. Remove it, rinse the interior with clean water, wipe with a soft cloth, and avoid hard brushes that scratch. Reinstall after cleaning.
Purified tank (sterilizing pitcher): The 1L removable pitcher is pull-out, food-grade Tritan, dishwasher-safe. Clean it regularly. Remove and rinse with clean water, wiping the interior with a soft cloth. The bottom Helix UV lamp cycles automatically for long-lasting bacteriostasis.
Body: Wipe with a soft dry cloth; avoid corrosive cleaners or hard cloths. Keep the unit away from direct sunlight.
Waste Water
Ratio & handling: The remaining water in the raw tank is not really "waste" — it flushes impurities off the filter and helps maintain filter life. When the unit prompts a water change, pour out the waste, refill with fresh water, and continue. Not for drinking, but the waste water can be reused for cleaning or watering, so nothing is wasted.
Cleaning & Descaling
Daily cleaning: Body — wipe with a soft dry or slightly damp cloth; no corrosive cleaners, steel wool or hard brushes; never immerse or hose the whole unit. Raw tank — remove every 1-2 weeks, rinse and wipe. Pitcher — the 1L removable Tritan pitcher is dishwasher-safe; the bottom Helix UV lamp cycles automatically. Spout — wipe the drip tray and spout with a soft cloth and keep dry.
Descaling (H05 self-clean mode): Over time the RO membrane clogs with calcium/magnesium and purification slows. Run a self-clean/descale cycle every 3-6 months depending on local water quality; it takes about 1 hour:
1. Make descaler: in a 250mL+ container, add citric acid descaler, run ~200mL of 98℃ hot water and stir until fully dissolved.
2. Enter mode: long-press the volume key ~10s; after the second beep the raw-water TDS shows "H05" to start self-cleaning.
3. When the screen shows "01", remove the raw tank, long-press "Dispense/Stop" 5s to drain (shows "02"); once empty, fill the raw tank with tap water to the max line and pour in the citric-acid water.
4. When draining shows "03", replace the raw tank; "04" starts auto pipe flushing for ~30 minutes.
5. When "05" appears, remove the raw tank, pour out the dirty water, refill and replace; after "End", it exits automatically after 5s.
6. After exit, long-press "Dispense/Stop" to drain 2-3 times before normal use.
If you enter "H05" by mistake, long-press the volume key ~10s until "End" appears to exit manually.
FAQ
Water Quality
White foam is normal — it is fine bubbles that disappear when left to stand, and the water is safe to drink. Two causes: ① pressure change — during purification, pressure pushes water through the membrane and dissolves some air; when water dispenses, pressure drops and the dissolved air comes out as bubbles; ② temperature change — warmer water holds more air; as hot water cools, air comes out as fine bubbles.
The G3Pro uses RO reverse osmosis + natural mineral filter media, adding suitable natural media to simulate high-quality source water. It purifies first, then mineralizes, releasing beneficial minerals and improving taste. The output is sweet mineral water that needs no boiling and is safe to drink directly at room temperature.
Operation
Long-press the "60mL" volume icon 5 seconds and release after the beep to toggle child lock. When on, the child-lock icon lights and the raw-water TDS shows "LOC"; no dispensing can occur. It is off by default on a new unit or after a power reset.
The G-Radar night light only activates in standby (screen dimmed) when you place a cup under the spout. It will not trigger while the screen is on. This is by design, to wake the screen and lights automatically for nighttime water.
Poor local water quality or not changing the raw water in time can push raw TDS to 999; the unit beeps and prompts a water change. To turn off the alert tone, long-press the "85℃" key 5s (to toggle). However, high raw TDS accelerates filter consumption — change the raw water promptly when prompted.
The unit uses RO reverse osmosis; the booster pump runs normally during purification and makes some sound — this is normal. It goes quiet once purification stops. The ~15-second spiral convection flush after purification is also slightly audible and protects filter life. Place the unit on a flat surface or a soft mat to reduce resonance.
Filters
A swollen outer plastic wrap on a new filter is normal. After production, filters are inflated and sealed for air-tightness testing and faster filtration, which preserves them better. Bewinch uses double-layer sealing; as long as the seal is intact, it is safe to use.
If the filter indicator does not change within 30s after screwing in, pull it out and reinsert, repeating until it auto-resets. If it still won't reset, check that the bottom chip contacts are clean, or contact the store where you purchased. Each chip resets only its own filter once; double-check the filter model before replacing.
Stage 1 PP cotton and Stage 3 post-carbon are recommended every 6-8 months; the Stage 2 RO membrane every 2-3 years. Actual life depends on power-on time, local raw-water TDS and daily dispensed volume; the panel reminds you. Unopened filters have a 5-year shelf life — store in a cool, dry place.
Product Features
The G3Pro's 26cm shallow-edge body with an easy-lift side tank greatly reduces countertop depth, suiting small homes and kitchens with limited space. The G-Radar 2.0 night light lights the screen automatically when you get water at night for peace of mind.
After-Sales & Service
The G3Pro carries a 2-year nationwide warranty. Within the first year from purchase, performance faults are covered by a "replace-not-repair" service. For support, contact the store where you purchased, or reach the store through the Bewinch official mini-program.
The G3Pro is a no-install design — plug in and use, with no drain connection; waste water stays in the raw tank and is poured out on water changes. If you'd like guidance for first use, you may book a free on-site service via the Bewinch official mini-program or by contacting the store where you purchased.
Filter Reset & Replacement
The G3Pro uses sensor reset. Long-press the filter-reset key 5s; all three filter-life indicators flash fast to enter reset mode. Hold the anti-counterfeit sticker on the new filter near the NFC sensing area on the right side of the unit; a beep means reset is done. Each chip resets only once — reset only when the system prompts. After replacing, long-press "Dispense/Stop" 5s to drain 2-3 times before normal use.
① Open the top cover: press and slide it forward. ② Remove the old filter: grip the handle, turn the pointer from "locked" to "unlocked" and lift out. ③ Install the new filter: align the pointer with "unlocked" and insert into the matching slot, then turn to "locked" (confirm it cannot be lifted). After fitting, reset as above and drain 2-3 times.
Non-original filters may lack material hygiene assurance and have reduced filtration and sealing performance, which can cause abnormal water quality, safety risks and shorter unit life. Buy replacements from official authorized channels when a filter alarms; filters from unofficial channels cannot be reset and the unit will not work.
Use & Cleaning
Place a heat-resistant container under the spout, long-press the "Sterilize/Clean" or "Custom/Clean" key 5s to start self-cleaning. The unit cleans for ~30s, automatically dispensing ~100mL of 98℃ hot water, then stops on its own; press the key again during the cycle to cancel. Run a clean cycle once if the unit has been unused for over 3 days.
From the heat-capacity formula Q=cmΔt, a higher target temperature means a larger temperature difference and more energy needed. The unit's max power is limited, so to reach the set temperature quickly it reduces the water flow — the hotter, the smaller the flow. This follows energy conservation and is normal.
To avoid re-contaminating purified water, the unit uses a sealed structure. Heating water to 100℃ boils it into steam, raising pressure inside the heating tube. So countertop purifiers usually heat above 90℃ but below 100℃. The unit uses deep RO filtration; the output meets national direct-drinking standards and is safe to drink even unboiled.
Clean every 2-3 months. ① Remove the raw tank and open the unit top cover and purified-tank lid; ② long-press "Dispense/Stop" 5s to drain, then it stops automatically; ③ wipe the purified-tank interior with a clean lint-free cloth; ④ refill the raw tank and wait for auto purification; ⑤ drain 2-3 more times.
First pour out the remaining raw-tank water and refill with municipal tap water. Power on and drain all internal water; wait until the purified tank fills, then empty it; repeat 3 times before normal use.
Water Quality & Waste Water
Waste water is not sewage — it is concentrated water the RO uses to flush impurities off the membrane, to maintain filter life. Raw water and waste share one tank: the raw inlet is on top, the waste outlet on the bottom, so they naturally separate by density; combined with filter flush technology, waste water is not re-filtered. Purified water from four-stage filtration is stored in the purified tank to keep drinking water safe; when raw-water concentration reaches a threshold, the unit prompts a water change.
Modules & Iced Drinks
The MixHub base uses Bewinch's self-developed water/electric transfer — no repeated plugging/unplugging. A module swaps in about 5 seconds; one coupler works for all modules.
No. Put only purified water in the bottle. Do not add ice, fruit, syrup or other liquids — they may block the valve and create a safety risk. Never use non-Bewinch bottles or cylinders.
Yes. With no module fitted, one bar means low-level; with the purification module fitted, one bar is the pitcher's protected water level (~5-10mm), meaning there is still internal water available. It does not affect normal dispensing.
The ice module makes ice in about 6-8 minutes (~6 min at 25℃, +8s per 1℃). Each batch makes 9 bullet-shaped ice cubes; the bin holds 40-50. Because it has a compressor refrigeration system, let the unit stand upright for 2 hours after shipping before first use.
① Make sure the CO₂ cylinder is installed and the cylinder-base handle is closed and locked; ② push the bottle forward against the metal rod and turn clockwise to lock; ③ press the gas button to make sparkling water. One standard cylinder makes about 200-300 glasses (300mL each). Buy original cylinders only from official channels.
The unit has a light-sensor (photosensitive) mode: when the room is too dark it automatically stops ice-making to reduce noise. It does not stop instantly when you cover the sensor — there is a delay. This is a normal energy-saving design; to make ice at night, place the unit where there is light or turn on the room light.
Normal. The RO booster pump compresses air in the water into fine bubbles; on dispensing the pressure releases and they expand into a visible white mist that disappears when left to stand. It does not affect water quality and is safe to drink; it fades after repeated flushing.
On first use the refrigeration/ice-making takes longer. With the raw tank above 1/2 full, wait 20-30 minutes for full cooling before taking cold water or ice.
Troubleshooting
Phenomenon: Pressing dispense gives no water or very slow flow.
Possible causes: Raw tank empty, purified tank not full, filter clogged, child lock on, or wrong temperature/volume setting.
Solution: ① Check raw-tank level and refill; ② wait for purification (~10 min); ③ check filter life and replace if due; ④ unlock child lock; ⑤ confirm settings. If still no water, contact the store where you purchased.
Phenomenon: Puddles under or around the unit.
Possible causes: Raw/purified tank not seated, tank seal aged/misplaced, drip tray overflowing.
Solution: ① Reinstall tanks until they click; ② check seals; ③ empty the drip tray promptly. If it still leaks, unplug immediately and contact the store where you purchased — do not disassemble.
Phenomenon: Set high but output is cool, or heating slows.
Possible causes: High-altitude low boiling point (above 1,800m), heating chamber not recovered after long dispensing, clogged filter, unit just powered on.
Solution: ① At altitude, set temperature may not be reached — normal; ② wait 3-5 min after long dispensing; ③ check/replace filters; ④ dispense a cup first to warm the lines. If still abnormal, contact the store where you purchased.
Phenomenon: Plastic, disinfectant or other off-taste.
Possible causes: New unit under-flushed, filter due, tanks uncleaned, raw water quality worsened.
Solution: ① Complete full flushing (cold drain ×3, 45℃ ×1-2, 98℃ ×1-2); ② check/replace filters; ③ clean raw and purified tanks; ④ if raw water suddenly worsened, replace all raw water.
Phenomenon: Noticeable noise during purification or heating.
Possible causes: Raw tank empty causing dry run, unit not level, filter not seated, normal pump hum.
Solution: ① Check raw-tank level; ② level the unit on a flat surface; ③ open the cover and reseat filters; ④ mild pump/heating hum is normal. If there is clear rattle or vibration, contact the store where you purchased.
Phenomenon: Black screen or no touch response.
Possible causes: No power, child lock on, screen-off eco mode.
Solution: ① Check plug and outlet; ② if locked, long-press 60mL 5s to unlock; ③ tap any key to wake. If the screen stays dark or touch is abnormal, contact the store where you purchased.
Phenomenon: Raw TDS reads 999, buzzer sounds, low-water light on.
Possible causes: Poor local water or stale raw water; even after changing water, it still reads 999 because no purification has run.
Solution: ① Replace all raw water; ② after refilling, dispense so the unit starts purifying — the probe detects new water and TDS drops; ③ to silence the alarm, long-press "85℃" 5s (toggle).
Phenomenon: After long disuse, the screen fault indicator lights.
Possible causes: Normal reminder from residual water changing in the lines after sitting.
Solution: No need to worry. Just press "Dispense/Stop" to dispense, or remove the pitcher, empty and reseat it. For reuse after long idle, run a full flush first.
Phenomenon: White powery crystals form on the raw-tank wall over time.
Possible causes: Regional water-hardness differences cause limescale.
Solution: ① Mix 5-10g food-grade citric acid in a cup of ~65℃ hot water until dissolved; ② fill the raw tank with tap water and add the solution; ③ soak 30-60 min and wipe with a clean cloth until scale lifts; ④ pour out and rinse thoroughly.
Phenomenon: Screen shows E01; unit stops dispensing and purifying.
Possible causes: Inlet water-temperature sensor abnormal, usually from very low ambient temperature (common in winter); the sensor near 0℃ triggers self-protection.
Solution: Move the unit to a warm room for 1-2 hours; E01 clears once the sensor recovers. If it does not clear in a warm environment, the sensor or control board may be faulty — arrange service by calling 400-828-0808.
Phenomenon: Long purification or noticeably slower.
Possible causes: Raw tank empty, filter clogged/due, high raw TDS, low ambient temperature, pump fault.
Solution: ① Refill to max line; ② check/replace filters; ③ replace all raw water and repurify; ④ keep ambient 5℃-35℃. If still not purifying, contact the store where you purchased.
Phenomenon: Leak at the purified tank / pitcher connection.
Possible causes: Pitcher not seated, seal aged/misplaced.
Solution: Reinstall the pitcher until it clicks and check the seal. If it still leaks, contact the store where you purchased.
Phenomenon: Drip tray overflows or gets dirty.
Possible causes: Spilled water and residual line water collect in the tray; needs periodic cleaning.
Solution: Remove the tray as shown, empty and wash, then replace. Check and clean regularly.
Phenomenon: Taking hot water pops E02 and stops flow.
Possible causes: Outlet temperature sensor open circuit (reads 100℃), or outlet NTC cracked and letting in moisture.
Solution: Restart and see if it recovers; if it recurs, the outlet NTC is likely cracked/moist — contact service to replace or repair the sensor by calling 400-828-0808.
Phenomenon: Screen shows E03 (outlet sensor short, reads 0℃) or E04 (outlet sensor open, reads 120℃).
Possible causes: Outlet temperature sensor abnormal.
Solution: It clears automatically once the fault is fixed; if E03/E04 persists, contact service to check the outlet temperature sensor by calling 400-828-0808.
Phenomenon: Screen shows E07, drain abnormal prompt.
Possible causes: Continuous drain for 10 minutes still not complete; usually a blocked drain line.
Solution: Power off to clear; check the drain line for blockage. If it recurs, contact service by calling 400-828-0808.
Phenomenon: Screen shows E11.
Possible causes: Heating fault — after 20s it still hasn't reached half the target temperature, usually from too-cold raw water.
Solution: Power off to clear; confirm using 5℃-35℃ municipal tap water. If it recurs, contact service to check the heating system by calling 400-828-0808.
Phenomenon: New unit shows raw 04, pure 03 and does not purify.
Possible causes: Factory default — before a new unit passes water, all show raw 04 / pure 03 by default; not a fault, as no water has really passed through.
Solution: ① If the water-change light shows 0403: check the raw-tank float wasn't left out; reseat the tank a few times; ② If the light is off but still shows 0403: complete the new-unit flush and purify normally; the display updates. If it still won't purify, the booster pump or waste-water solenoid may be faulty — contact service.
Phenomenon: Raw tank has water but the unit prompts a change or shows empty.
Possible causes: ① Tank float not fitted or weak magnetism; ② poor tank-to-body contact; ③ TDS 999 alarm.
Solution: ① Fill to max and check the float seats and floats in full water; ② reseat the tank firmly; ③ on TDS 999, after refilling, dispense so purification runs — the probe detects new water and TDS drops.
Phenomenon: Hot water flows thin and fluctuates, with a little steam.
Possible causes: Instant-heat near-boiling heats water to ~100℃ in the tube, forming steam; for accurate temperature the flow is thinner than ambient — normal.
Solution: A normal physical effect; no action needed. At altitude it may be more noticeable; hold the cup close to the spout.
Phenomenon: Hot water spits or splashes when dispensing.
Possible causes: At altitude the boiling point drops, steam volume in the tube rises and exits with the flow; even ambient-set units may briefly do this with very cold raw water.
Solution: Hold the container close to the spout. At altitude, watch for splashing on first use; some areas may not deliver the highest-temperature level reliably.
Phenomenon: Seepage from the raw-tank bottom.
Possible causes: Bottom inlet/outlet valve loose, not fitted, or scaled.
Solution: Refit the bottom valve and tighten; fill the tank, wipe the bottom and test it alone. If still leaking, gently rotate/press the bottom inlet/outlet valve until it stops; if needed, contact the store where you purchased for guidance.
Phenomenon: New unit's spout keeps dripping.
Possible causes: Debris in the new-unit lines preventing the valve from sealing.
Solution: Drain a few times to flush out debris. If it still drips after several drains, contact service.
Phenomenon: Leaking and noise after replacing or fitting a filter.
Possible causes: Filter not tightened or seated; refitting an old filter may seal poorly.
Solution: Power off, open the cover, remove each filter and reseat it firmly. Use new filters — an old filter may show restored bars but loses purification efficiency and speed.
Phenomenon: Screen normal, but the unit beeps nonstop during dispensing.
Possible causes: Heating element or diaphragm pump issue.
Solution: Contact service to inspect the heating element or diaphragm pump by calling 400-828-0808.
Phenomenon: Display abnormal, e.g. temperature icon flashing, screen blacking then recovering.
Possible causes: Display control module abnormal.
Solution: Restart and observe; if it recurs or stays black, contact service to replace the display module by calling 400-828-0808.
Phenomenon: Purified-volume light turns red, overflow prompt.
Possible causes: Purified tank/pitcher not seated or poor contact, triggering the overflow sensor.
Solution: Reseat the purified tank/pitcher firmly, then drain (dispense) to clear the overflow display.
Phenomenon: Raw TDS reads lower than purified TDS.
Possible causes: ① You poured purified water into the raw tank, so raw TDS is naturally low; ② new unit under-flushed, internal lines not clean; ③ when raw water is very pure, the RO makes little waste and flushes the purified probe less, so the purified value may read slightly higher.
Solution: ① Use municipal tap water as raw water; ② complete a full flush; ③ after a week of higher-TDS tap water, raw will read above purified — normal, no impact.
Phenomenon: After airing and repeated boiling, a new unit still smells strong.
Possible causes: New filters and lines may carry a slight odor.
Solution: Open the top cover and purified tank, leave open 24 hours. If it persists, identify the source (raw or purified tank) and soak with brewed citric acid in the tank.
Phenomenon: Green moss-like growth on raw or purified tank walls.
Possible causes: Airborne algae spores enter the water and grow in bright places.
Solution: Move the unit away from light, clean tanks promptly, and soak/wipe tank walls with citric-acid solution.
Phenomenon: After moving the raw or purified tank mid-purification, air lock and leak appear.
Possible causes: Moving a tank while purifying lets air into the water lines.
Solution: Never move raw/purified tanks while purifying; wait until purification finishes or power off / until a water-change prompt before moving tanks.
Phenomenon: After replacing, resetting by NFC gives no beep near the sensing area; the light still flashes.
Possible causes: ① Not within the 30s reset window; ② anti-counterfeit sticker not near the right-side NFC area; ③ filter chip not sensed or not screwed in.
Solution: Long-press the filter-reset key 5s until all three indicators flash, then hold the new filter's sticker near the right-side NFC area; a beep means done. If no response, pull and reinsert and retry. Each chip resets only once — reset only when prompted.
Phenomenon: Pressing self-clean gives no response or won't enter mode.
Possible causes: ① No heat-resistant container under the spout; ② wrong press (must long-press, not tap); ③ unit in child lock or purifying.
Solution: Place a heat-resistant container under the spout and long-press "Sterilize/Clean" or "Custom/Clean" 5s; the unit dispenses ~100mL of 98℃ hot water and ends; press again to cancel. Run a clean cycle if unused over 3 days.
Phenomenon: Insects found inside or at the base.
Possible causes: The base has drainage guide holes (to prevent internal leaks), so insects can enter when the environment has many.
Solution: ① Place the unit in a clean, ventilated, dry spot and clean it regularly; ② put 1-2 non-toxic repellent sachets around the four feet, kept flat and stable. The internal water path is fully sealed, so water quality is unaffected.
Phenomenon: After fitting the ice-water or ice module, no cold water or ice comes out.
Cause: First-use cooling takes long and the unit hasn't chilled enough, or purified water level is too low.
Solution: With raw tank above 1/2 full, wait 20-30 minutes for full cooling; ensure the pitcher has at least one water-level bar. If still not cooling, contact the store where you purchased.
Phenomenon: No bubbles after pressing the gas button.
Cause: Cylinder empty, cylinder-base handle not closed/locked, drip tray full, or bottle not seated.
Solution: ① Check the cylinder has gas and replace with an original cylinder from official channels; ② confirm the cylinder-base handle is closed and locked; ③ empty the drip tray; ④ reseat the bottle and turn to lock. If still no gas, contact the store where you purchased.
Phenomenon: Long time after installing the ice module, no ice.
Cause: Ice module power switch off; ice won't release; refrigeration fault; dark room triggering light-sensor eco mode; pitcher level below one bar so no water feeds the ice tank.
Solution: ① Turn on the ice-module power switch; ② if ice won't release or the refrigeration system is faulty, contact service; ③ turn on a light or move to a brighter place; ④ wait until the pitcher rises above one bar and it auto-feeds the ice tank.
Phenomenon: No ice at night or in a dark room, but normal by day.
Cause: The light-sensor eco mode stops ice-making in the dark to reduce noise.
Solution: Normal design. To make ice at night, place the unit where there is light or turn on the room light.
Phenomenon: Water at the bottom of or around the ice module.
Cause: Module not fully installed/sealed; or the drain plug not refitted after manual draining.
Solution: ① Install the ice module until its top is level with the main unit; ② refit the drain plug. If still leaking, unplug and contact the store where you purchased.
Phenomenon: Seepage around the MixHub base after replacing or installing a module.
Cause: The module isn't fully pressed onto the base, so the water/electric coupler isn't sealed.
Solution: Remove the module, realign, press straight down until you hear a click and the module top is level with the base, then use it. If it still leaks, contact service to check the seals.
Phenomenon: Noticeable noise during ice-making.
Cause: The compressor running and ice dropping into the bin are normal sounds.
Solution: Normal. At night the light-sensor auto-stops ice-making to reduce noise.
Phenomenon: When the pitcher shows one water-level bar, the ice/ice-water module stops.
Cause: Low-level protection stops the ice module.
Solution: Wait until the main unit purifies and the pitcher level rises; ice-making/cooling resumes automatically. With no module fitted, one bar is just a low-level reminder and internal dispensing still works.

Practical Self-Help Tips
| Slow purification / no water / intermittent (suspected air lock) | Power on until it purifies (pulsing sound), open the cover, pull filters; use a chopstick to gently poke the bottom hole of each filter to release air (if the chopstick meets resistance, air lock is confirmed — water may spurt from the bottom; keep it away from your face). Vent each filter, refit, wipe the table, close the cover. |
| Plastic/off-taste after new unit or water change | Open the cover and purified-tank lid, air out 24h; if it persists, soak the purified tank with brewed food-grade citric acid, then drain 2-3 times; ensure a full flush (cold drain 3-5×, warm flush 1-2×). |
| Spout drips a few drops after removing the cup | Usually residual carbon powder or debris in new-unit lines; drain 3-5 times and it normalizes. If it continues after use, contact the store where you purchased. |
| White floating particles in water | Food-grade grease residue in lines after a new unit or filter change is normal; drain a few times (5-10 cups) and the particles vanish; harmless. |
| Screen numbers jump / touch erratic | ① Wipe water off the screen (capacitive touch triggers when wet); ② check for unstable voltage, try a dedicated outlet; ③ if it keeps flickering, the touch film may be faulty — call 400-828-0808. |
| Press dispense, no water, display normal | ① Check the top cover is fully pressed down (an unlatched cover triggers a safety lock); ② unplug 1 min, replug; ③ confirm raw tank has water and the float floats; ④ if all fail, the diaphragm pump may be faulty — call 400-828-0808. |
| Does the purified tank need regular cleaning? | Yes, every 2-3 months: ① remove raw tank, open covers; ② long-press "Dispense/Stop" 5s to drain; ③ wipe purified-tank wall with a lint-free cloth; ④ refill raw tank, wait for auto purification; ⑤ drain 2-3 times. |
| Hot flow intermittent with steam | Spin-flow heating heats water to near 100℃ in-tube, producing steam, so the flow is thinner than ambient and may fluctuate — normal. At altitude try 85℃. |
| Insects at the base | The base has drainage guide holes; keep the unit in a clean, ventilated, dry place; put 1-2 non-toxic repellent sachets around the feet. The internal water path is sealed. |
| Still plastic smell after flushing — deep deodorizing | New wetted plastics may retain a slight odor after factory deodorizing and sealed packaging — normal. Air the purified tank 12-24h, then flush. If it persists, use the "dish-soap method": dilute food-grade dish soap, cycle it through the purified tank, then drain 3-5 times with clean water. See official video tutorials. |
| White scale / crystals on raw-tank wall | Normal limescale over time: mix 5-10g food-grade citric acid in ~65℃ hot water; fill the tank, soak 30-60 min; wipe until scale lifts; pour out and rinse. |
| New filter outer packaging swollen | Normal: filters are air-tightness tested and inflated before sealing for better storage and filtration. As long as the seal is intact it is safe. Double-layer sealing prevents contamination in transit. |
| Loud purification noise on first use | Normal: new filters, booster pump and lines hold lots of air; the pump compressing air is loud. Repeated purification and draining fully wets the lines and the noise drops. Place on a flat surface or add a soft mat. |
| Black powder in tanks after a new unit passes water | Normal: carbon-block filters are sintered from carbon powder and food-grade binder; a little carbon powder flushes out on first use — non-toxic. If in the raw tank, flush 3-5 times; if in the purified tank, rinse and wipe, then drain a few times. |
| Cloudy raw water with green/brown particles | Usually algae spores or pipe sediment from aging water mains, more common in summer. The raw tank holds unpurified tap water; cloudiness does not affect output — after the RO membrane (0.0001 micron), microbes, bacteria and impurities are removed. Clean the raw tank regularly. |
| Leaks under/around the unit | ① Close the inlet valve (if any), stop water and unplug; ② self-check for spills during dispensing or overfilling past MAX; ③ open the cover, reseat the three filters; ④ wipe the table and base and observe. If it leaks again, contact the store where you purchased. |
| What is TDS? Why does it change each time? | TDS (Total Dissolved Solids) is the total of dissolved substances in water; higher means more minerals/impurities. It is set by the raw-water quality, not fixed. Residual old water in internal lines mixes with new water, so readings may run slightly above tap water. After refilling, dispense a cup so purification runs and the TDS probe detects the new water. |
| Raw-tank water getting concentrated / waste water | The RO membrane is 0.1nm precision; to avoid impurity buildup clogging the pores, some water flushes the membrane surface and returns to the raw tank as "waste". It is only slightly saltier than tap water, not sewage. Each water change, pour out all remaining raw water and refill fresh; don't reuse waste water. |
| Fixed-volume dispensing slightly off | A little water remains in the lines, so some error is normal; hot-water error may be larger as flow speed changes with temperature. Measure with an accurate measuring cup; this is within normal tolerance. |
| Vertical line/mark on the outer shell | This is a natural knit line from plastic fusion in injection molding — common industry-wide, no effect on use or looks. We keep improving the process to reduce it. |
| How is filter life calculated? Must replace when due? | Three dimensions: ① power-on time (like a shelf life, decays even unused once wetted); ② raw TDS change (worse water consumes faster); ③ cumulative dispensed volume. The reminder is a recommended cycle, not a hard deadline — but don't wait until fully clogged, or the pump may overload or lines may rupture. |
